Your Diagnosis

Before revealing the machine’s verdict, predict the BS score for each signal. Higher = more BS (more fluff, less verifiable substance). Drag each slider, then submit to compare your judgment against the engine.

Information Density 0 / 30
Read the Narrative & headings: do hard facts (prices, dates, numbers) outweigh fluff power-words?
Semantic Coherence 0 / 20
Compare the homepage promise against the sub-page reality. Do they hold the same line?
Trust & Proof 0 / 20
Weigh review mentions against actual external proof links. Claims without verification = theatre.
Commodity Fingerprint 0 / 15
Check headings & narrative against the industry clichés in the setup above.
Identity & Authority 0 / 15
Inspect the schema: is there real Organization/Person identity with sameAs links, or gaps?
Your predicted BS score 0 / 100
💡 Stuck? Reveal the heuristic lens — how the deterministic page-auditor reads each signal (no AI, pure pattern rules)

These are the structural rules a local, deterministic auditor applies — the same lens you can use to judge each signal. They describe what to look for, not this company’s result.

Information Density

Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.

Semantic Alignment

Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.

Trust & Proof

Count trust words (review, testimonial, rating, verified) against real outbound proof links (Google, Trustpilot, Clutch, G2, Yelp). Lots of trust language with zero verification links is trust theatre. Unlinked logo galleries count against it.

Commodity Fingerprint

Look at how much sentence length varies. Natural writing varies its rhythm; templated or mass-produced copy is statistically uniform. Very low variation reads as commodity content — unless unique named entities break the pattern.

Identity & Authority

Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.

Want to apply this lens yourself? The free BS Indicator Chrome extension runs these heuristic checks live on any page. Bear in mind it is a single-page, deterministic tool — it relies only on pattern rules for the page in front of it and does not perform the cross-page semantic correlation this audit uses, so its readout is a starting lens, not the full verdict.

Polyfibre is a high-substance manufacturer suffering from an identity and proof deficit. It provides more raw technical data than 90% of competitors, yet fails to provide the basic digital credentials (schema, pro-endorsements, verified reviews) required to bridge the gap between manufacture and prestige. It is a low-BS technical site that simply forgets to prove its social and professional status.

Immediately implement Product and Organization schema across all pages to provide structured technical data to search engines. Create a ‘Pro Player’ or ‘Testimonials’ page that links the ‘Creating Winners’ claim to specific, named athletes with verifiable rankings. Link technical claims like ‘doubled durability’ to a downloadable test report or comparative chart to move them from ‘fluff’ to ‘fact.’ Replace generic personification in product descriptions (like the Panthera copy) with more focus on the specific duplex-polyester blend ratios to maintain the technical authority established elsewhere.

The website identifies as a manufacturer of tennis strings and sports equipment, which fits broadly under the Sports category but diverges significantly from the Fitness/Gym patterns provided. The content is product-focused rather than service-focused, emphasizing manufacturing specifications over membership or training services.

“The BS score of 38 is driven primarily by the lack of external verification and authority gaps. While the technical content is robust (low information density penalty), the absence of structured data and the presence of unverified review counts in the meta-data increased the Trust and Proof and Identity and Authority penalties. The site is a 'Low BS' entity overall, as its primary signal and substance are well-aligned.”
